Tojall whom it. nmg concern a Be it known that I, Nrorrons's S. Vnnnnn, of Troy,

IoHoLAss, V'EDD'ER,

OF TROY; NEW YORK..,

Letters Patent No. 97,731, dated December 7, 1869; antedated November 30, 1869.

" cooxmees-rovn.

The Schedule referred to in these Letters Patent and making part of the same.

in the countyof Rensselaer, and Stateof' New York, have invented a new and usefulImprovement in Cookin-g-Stoves; and I do hereby declare the following to be a full and correct descriptionof the same, suiticient to enable others skilled in the manufacture to which my invention appertaius to fully understand and constmct the same, reference being had to the accompanying drawings, which make part of this specificatiou, and in whicha v i a Figure 1 is a front wiew of improvement;

Figure 2 is a plan of the same, the top plate of the stove being removed; and a Figure 3 is a vertical section in line a: x, fig. 2. Like letters of reference indicate like parts in the several figures.

y The nature of my invention consists the stove, showingmy in providing a hot-air chamber in front of thefire-place, in which the cold'air entering, is heated before reachingthe place of combustion, the said chamber being divided by partitions in such amanner-that the current of air entering the chamber is forced upwardly in the centre compartment, which is closed at the bottom,over the partitions, thence downwardly through the compartments ateach side of the middle one, and strikes the fire from under thegrate at the ends, instead of the centre, thus aiding the process of vcombustion at the,

points where it is most feeble. v A, in the drawings, represents thefire place of a cooking-stove.

.In front of the fire-place, I form a chamber, 6, by means of a plate, 0, which chamber is divided intothree compartments, by means of, partitions d and 0.

These partitions do not reach up to the top plate of the stove entirely, but leave a suflicient space to communicate with the compartments at the top. The

a middle compartment is larger than the others, and

is closed at the bottom, while the end compartments are open at the bottom, communicaiing with the fire-' place. 7

Theplate c is provided with opeulngs f, in the space between the partitions d e, through which the admission of air is regulated by a slide, g.

The entire front of the stove being closed, it will be seen that the draught must come through the openings f, and compartments of chamber 0, to the fireplace. The-object of this chamber is to heat the air while on itsway to the place of combustion, as hot air, as is'well known, aids combustion a great deal more than cold air. Furthermore, the draught is usually strongest in the' centre of the fire, whereby the process of combustion is accelerated in the centre and retarded at the ends of the fire-place.

I By mymethod of admitting the draught at the ends of the'fire-plaee instead of the centre, I obtain an equal result of combustion at the ends as in the centre, the air rushing from and through the ends to the centre.

The openings 9, being uncovered, the air passes into the middle compartment, and, not being able to pass out at the bottom, it rushes over partitions d c, into the end compartments,- where it is forced downward to the ends of the fire-place, it being heated during the entire passage through the compartments.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent,is-

The hot-air chamber G, provided with partitions d e,

openings f, and regulating slide 9, constructed and arranged as described, whereby the air is first heated, and then passed into the grate at the vends, substantially as and for the purpose set forth.'
